High-Volume Soluble Manganese for Hydroponic, Fertigation & Soil Programs
Tecmangam Manganese Sulfate Soluble Powder is Prince Agri's commercial-scale water-soluble manganese source — delivering 32% manganese (Mn) and 18% sulfur (S) in a fine powder that dissolves completely for use in hydroponic nutrient solutions, fertigation systems, and foliar programs. The 55 lb bag is sized for high-volume operations that need a reliable, cost-effective manganese input at scale.
Manganese is essential for photosynthesis, enzyme activation, and nitrogen metabolism. Deficiency causes interveinal chlorosis in young leaves and reduced plant vigor — particularly in high-pH or leached soils. Tecmangam corrects it fast, with immediately plant-available Mn in every application.
Guaranteed Analysis
- Total Manganese (Mn): 32%
- Water Soluble Manganese (Mn): 32%
- Sulfur (S): 18%
- Derived from: Manganese Sulfate Monohydrate (MnSO₄·H₂O)
Application Rates
- Hydroponic stock solution: Dissolve 0.9–1.0 g per liter of water; apply at 2.5 mL/liter (9–10 mL/gallon) to achieve ~1.5 ppm Mn in working solution
- Constant-feed systems: Target range 0.1–2.0 ppm Mn in nutrient solution
- Foliar: 1–3 lb/acre dissolved in water
- Soil broadcast: 20–60 lb/acre pre-plant or at planting for manganese-deficient soils
- Banding / side-dress: 10–30 lb/acre for in-season correction
Key Features
